Description

Setup: 6 + 1 nodes EMR cluster with m4.4xlarge instances

Job submission fails in most cases (but not all of them):

[hadoop@ip-172-31-28-17 flink-1.5.0]$ HADOOP_CONF_DIR=/etc/hadoop/conf ./bin/flink run -m yarn-cluster -p 80 -yn 80 examples/batch/WordCount.jar --input hdfs:///user/hadoop/enwiki-latest-abstract.xml --output hdfs:///user/hadoop/output
